Sensitive beings, such as octopuses, need to take rests.

Mature female Giant Pacific Octopuses have 280 suckers on each arm—that’s 2240 suckers—each sucker containing thousands of chemical receptors. The sensitivity of an octopus’s suckers allow it to recognize different people based on the feel and taste of their skin.

Loving creatures: one octopus aquarist at the Monterey Bay Aquarium tells the story of having to work on a different exhibit for a month. When he returned, the octopus was so happy to see him, he crawled up his arms, out of his tank and around his neck to give him a big hug.
